Application filed November 17, 1921. Sen'al No. 515,888.

To uZZ whom it may concern Be it known that-I, GLARKSON A. Disnnow, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Holders for Insulating Units in Insulated Rail Joints, of which the following is a specification.

This invent-ion relates to new and useful improvements in insulated rail-joints generally, although more particularly to a holder for confining the insulating fibre.

The principal object of this invention-is to provide a simple and economical means for confining and protecting the insulation whereby it cannot escape when subjected to the loadsand pounds it receives incident to the trains passing thereover.

Another object is to provide a holder for the insulated bearing plate wherein the constructi on is such thata built-up unit may be readily manufactured and as such may be readil applied to joint-bars of commercial form.

Another object is to provide a holder for the purpose set forth which will permit of variations in the lengths of the bearing plates employed, and in the lengths of the spacingblocks between the bearing" plates.

Inthe drawings:

Figure l is a side elevation of a rail-joint embodying one form of my invention.

Figure 2 is a cross-sectional view thereof.

Figure 3 is avertical longitudinal sectional view taken through the complete holde' and insulating units.

Figure 4 is a perspective view of the holder showing the bearing plates properly assembled.

Figure 5 is a detail cross-sectional view showing a modified form of holder;

Figure 6 is a detail cross sectional view showing a holder equipped with a bearing plate having a curved rail-engaging surface.

Figure 7 is a detail sectional view illuscrating the improvement applied to both .the' head and base of a joint bar. 7

Like reference numerals designate corre sponding parts throughout the several views.

Primarily the invention comprises a holder applied to a face of the joint bar and S cured in such a manner as to prevent lateral or longitudinal displacement thereof, said holder affording means for supporting any with the under side of the rail head.

predetermined number of properly positioned insulating units, each of which units includes a metallic bearing plate having a direct bearing and supporting engagement This form of construction lends itself readily to a rolled length of bar of uniform section throughout, so that another advantagev of this typ of insulation in connectionwith economy of manufacture is that the same section of joint bar may be used for rails of diiierent fishing; heights, simply by varying the thickness of the bearing plates either in the head insulation or in the base insulation or in both. I

It will be understood that the principle of construction, embodied in the present invention is applicable to either the head or base of a oint bar or to boththe head and base of a joint bar, though preferably and usually employed as the active part of the head of the bar as'shown in the drawinps, but it should be noted that when bothhoad and base insulation-oft this type are used it forms a very simple insulated joint that can be applied to the rails in track as easily and quickly as an ordinary standard jointv lhis is of decided advantage when installing a joint in busy track. and where very-little time is allowed for the work.

In carryingforward this general feature of the invention. it will he understood that .the holder for th spaced insulating units may be of diitcrent formsof construction and secured to the joint bar in different ways, but since the essential features of the invention are well exei'nplilied by the figures of the drawings, the details of these drau ings willlnow be referred to, merely by way oi examples of the invention.

Referring 'to' the exan'lples shown in the drawings. the rails are designated by the numerals 5-,5 and the joint bars by the numerals 6-43; The'holder for one or more 'walls 9 9. A plurality ot'inetallic bearing plates lO are positioned within thechannel and each plate is seated in an insulating cup 11 formed of strips of fibre or the like, the bearing plates projecting above the walls 9.

The bearing plates are held against lateral movement by the walls 9-*9. fBp-acing blocks 12, preferably f metal are positioned in the channel and are respectively disposed between the bearing plates, and are rig dly secured to said. bar, preferably by welding. These spacing blocks fill the channel so that the outer surfaces of the blocks are sub cups 11 thus insulate the bearing plates from the bar and also from the spacing blocks.

One or more bearing plates maybe employed with each joint-bar and may be of any suitable length. Furthermore, the spaclng blocks may vary in length so as to vary the distances between the bearing plates. It Wlll thus be seen that the bearing plates are fixedly secured to the bar and that the bar is fixedly secured to the joint-bar.

In manufacturing these holders, a channel bar of considerable length is employed.

spacing block is positioned within the channel and at one end thereof. This block is then spot'welded or otherwise fixedly secured tothe bar. An insulating cup and. a

hearing plate are then positioned in the channel and against the inner end of the block. Another block is then positioned in the channel and held tightly against the opposite end of the bearing plate while said block is being spot welded or otherwise fixedly secured against outward and longitudinal movements relative to the bar, and by means of the walls 9 formed by the channel, the plate is held against lateral transverse movements relative to the bar. These operations are repeated until the entire bar has been traversed. The holder thus formed. is then cut into lengths, which may be coextensive with the joint-bars to which they are to be applied,

or may be in shorter lengths or in a number of short lengths each independently secured to the j oint-bars.

.ln securing the assembled holder to a. jointbar the channel. bar is preferably welded to the head of the oint-bar at spaced intervals only, as indicated by the numerals 15. Thus the channel barwouldnot, in its entirety, be

integral with the joiiiitbar and consequently would not be subjected to the strains, its lo' cation Wlth reference tothe horizontal neutral axis, would otherwise demand. The maximum top chord stresses would be in the broad area of the joint, bar head proper unkilerneath the channel bar orholder.

It will be also seen that by means of my improved built-up holders for the insulated hearing plates, not only a considerable saving in manufacturing is effected, but there 1s a saving in labor of installation of the oint in track since there will be fewer parts to assemble.

It has already been-pointed out that the invention is susceptible of modification with out departing from the spirit or scope thereofand one of these modifications is shown in Figure. 5 -whereinthe channeled holder is shown as being'of a double channeled format-ion the u 3 er channel rovidinp" for the V in. the improvement is illustrated as applied. to both the head and base of the joint bar.

In that form of construction it will be noted that the holding bar or channel bar may be welded to the joint bar on the inside,and as shown. this modification admits of. making the oint bar reversible; at the same time one which is provlded withtrack spikeclearance.

Other modifications and adaptations of the invention may be utilized and it will also be understood that minor changes in the form, proportion and details of construction maybe resorted to withoutdeparting from the invention as set forth in the appended claims.
